ABSTRACT:
A method for reducing excessive air inleakage and fuel consumption in open ring-type carbon baking furnaces is disclosed. This method consists in covering the preheat sections of the fire with covers. Each cover is preferably mounted on legs and a flexible sealing skirt is located all around to accommodate the height variations across each furnace section. There are usually more than one preheat section and the covers are identical in construction and dimension to minimize movement of the covers when the fire progresses. To further reduce fuel consumption, covers can also be placed on some of the cooling sections behind the fuel-fired sections and air can be blown or sucked into these sections to force cool these sections and to provide preheated air for combustion in the fuel-fired sections.
